I tried selling my 45a (described below) on eBay and got less than expected response. I've decided to try and restore it, since it's condition justifies the effort. There are two falts with the camera. The Graphex view finder is missing the rear lens and I'm sure that I'll be able to find one of those. The other thing is the range finder linkage where it contacts the focusing rail. I don't even know what I'm looking for. The article on this site talks about a Hugo Meyer rangefinder that has "a V shaped notch at the end of the rangefinder lever and a setscrew threaded into the focusing rail" The focusing rail in this camera has two screw holes and there is a screw missing from the rear one. There does not seem to be any "V" notch in the rangefinder arm which leads me to think that there may be some part missing that screws into the vacent hole and captures the linkage rod. Is there somebody that has a "a" or even a "b" that could take a digital close up of the attachment point for me? Or describe the connection.
